Replication

In addition to VM backups, you can create VM replicas with Veeam Backup & Replication. When you replicate a VM, Veeam Backup & Replication creates an exact copy of the VM in the native VMware vSphere format on a spare host, and maintains this copy in sync with the original VM.

Replication provides the best recovery time objective (RTO) values, as you actually have a copy of your VM in a ready-to-start state. That is why replication is commonly recommended for the most critical VMs that need minimum RTOs.
